I never used a smartphones and I don't want too much bells and whistles on my phone. My main priority is the sturdiness. It has to last me at least 5 years like my Nokia 6600. My 3310 is still working until now

So what's the next best thing to E71. I'm browsing through the Nokia E71/72 thread in another forum and they were talking about firmware installation etc. I just want a phone that I can automatically use when I turn it on with no need for a PC.
